Powdered milk or dried milk is a manufactured dairy product made by
evaporating milk to dryness. One purpose of drying milk is to
preserve it; milk powder has a far longer shelf life than liquid
milk and does not need to be refrigerated, due to its low moisture
content. Another purpose is to reduce its bulk for economy of
transportation. Powdered milk and dairy products include such items
as dry whole milk, nonfat (skimmed) dry milk, dry buttermilk, dry
whey products and dry dairy blends. Many dairy products exported
conform to standards laid out in Codex Aliment Arius. Many forms of
milk powder are traded on exchanges as been mashed or otherwise
broken down
